METHOD OF MAKING SHOVEL-BLANKS.

SPECIFICATION forming part of Letters Patent No. 405,416, dated June 18,1889.

Application filed April 4, 1889. Serial No. 305,920. (No model.)

To all whom it 11mg concern.-

Be it known that I, JAMES J. JOHNSTON, a citizen of the United States,residing at Columbiana, in the county of Columbiana and State of Ohio,have invented certain new and useful Improvements in Methods ofManufacturing Shovel-Blanks; and I do hereby declare the following to bea full, clear, and exact description of the invention, such will enableothers skilled in the art to which it appertains to make and use thesame.

My invent-ion relates to the art of making shovels, and has for itsobject the production of a double shovel-blank provided with single ordouble handle-straps.

The invention will be hereinafter described, and particularly pointedout in the claims.

In the accompanying drawings, which form part of this specification,Figure 1 represents a plan view of a bar for making blanks; Fig. 2, aperspective view of a blank severed from the bar, Fig. 3,a similar viewof a blank with the projections split for forming double handle-strapsat each end of the double blank; Fig. 4, a plan view of a doubleshovel-blank rolled or plated out; Fig. 5, a similar view of one half ofthe double blank after having been severed from the other half, and Fig.6 a plan view of the blank shown in Fig. 5 after having been pointed.

Reference being had to the drawings and the letters thereon,A indicatesthe bar for making double shovel-blanks, and is claimed in myapplication filed herewith, Serial No. 305,919. The bar is severed intosections on the lines a, and blanks B formed therefrom, each blankhaving a projection O on each edge thereof and directly oppositeeachother, and the body of the blank being of a length from end to endabout equal to the width of a finished shovel.

lVhen it is desired to make double shovelblanks with single handlestrapsat each end, the blank B is rolled in the direction of the projections O0 without splitting the projections; but when it is desired to makedouble shovel-blanks with double handle-straps the projections O O aresplit vertically, as shown in Fig. 3. Then each part b will form ahandlestrap when rolled out. The projection is split by a machinesuitable for the purpose, and a little cinder thrown between the partsI) when they are closed upon each other and the blank rolled as in thefirst instance. The blank B, after having been subjected tobreaking-down and reducing rolls, presents the appearance of a doubleshovel-blank D in Fig. l. The double blank is then severed. transverselyin its longitudinal center, as at c, and a single blank E, Fig. 5,produced. The blank E is then subjected to a pair of pointing-rolls anddrawn out into the form of the blank F, (shown in Fig. 6,) after which.it is sheared, stamped, and finished in the usual manner.

Having thus fully described my invention, what I claim is 1. The methodof manufacturing double shovel-blanks to the shearing-point, whichconsists in producing a bar with projections on its edges opposite eachother, severing the bar between the projections into sections of alength about equal to the width of a shovelblade, reducing the sectionsby rolling them into double shovel-blanks, then severing the doubleblanks transversely, and finally pointing each single blank separately,substantially as described.

2. The method of manufacturing double shovel-blanks, which consists insevering sections from a bar having projections on its edges oppositeeach other, splitting the projections, reducing the sections by rollingthem in the direction of the projections and foriiiing doubleshovel-blanks, then severing the double blanks transversely, and finallypointing each blank separately, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES J. JOHNSTON.
